  "summary": "On 17 September 2026, laboratory tests reproduced and then rejected unauthorized customer credit changes after the correction. A separate production check with a disposable unfunded account confirmed that customer credentials could not change credit, balances stayed unchanged and legitimate ledger reading still worked. A point-in-time ledger review found no unexpected grant-reference categories in the surviving records. That review is not a guarantee that no misuse ever occurred. Some broader laboratory reruns were deferred under a documented exception; the scope of this production check remains credit authorization.",
